摘　　要：高氧化还原电位酸性水（ＥＯＷ）是电解加有食盐蒸馏水时，在阳极产生氧化还原电位（ＯＲＰ）≥１０４０ ｍＶ， ｐＨ值≤３．６９，含有效氯＜８０ｍｇ／ Ｌ的水。经检测，水中食盐含量为 ５５０～ ９５０ ｍｇ／ Ｌ时，电解 １０ ｍｉｎ，该水 ＯＲＰ随食盐含量增加而升高；电解 ８～ １２ ｍｉｎ， ＯＲＰ随电解时间延长而升高。悬液定量杀菌试验表明，在 ２０℃下， ＯＲＰ为 １１５２ ｍＶ的该水，对不含蛋白胨悬液中枯草杆菌黑色变种芽胞作用４０ ｍｉｎ，杀灭率达１００％。杀菌效果随ＯＲＰ升高、温度上升而增强，因蛋白胨存在而减弱。Acidic water (electrolyzed oxidizing water, EOW) with high redox potential is the water with redox potential (ORP) ≥ 1040 mV, pH value ≤3.69 and containing available chlorine < 80mg / L, which are produced at the anode during electrolysis of distilled water containing table salt. Examination found that when the table salt content of water was 550-950 mg / L and electrolysis was carried out for 10 min, the ORP of water increased with increasing table salt content. When the eletrolysis time was 8-12 min, the ORP increased with prolonging electrolysis time. The suspension quantitative germicidal test indicated that at 20℃, the killing rate of Bacillus subtilis var. niger spores in suspension without peptone exposed to the water with ORP of 1152 mV attained 100%. The germicidal efficacy increased with increasing ORP and temperature and decreased in presence of peptone.
